Washington Herbicide Practice Exam

The correct answer is that the trigger handle is not a part of a nozzle. A nozzle is a device used to control the direction or characteristics of fluid flow, and its main components include the nozzle body, which houses the internal mechanics; the strainer or screen, which helps filter out large particulates from the liquid being dispensed; and the tip, which determines the shape and pattern of the spray produced.

The trigger handle, while important for operating a spray mechanism, is not technically part of the nozzle itself. Instead, it can be considered part of the overall assembly or device that uses the nozzle to spray liquids. This distinction is key; understanding the structure and function of a nozzle helps clarify its specific components and their roles in the spraying process.
